WINDOW-SCREEN.

SPECIFICATION, forming part of Letters Patent No. 699,157, dated May 6, 1 902. Application filed October 7, 1901. Serial No. 77,815. (No model.)

To all whom, it may concern.-

Be it known that we, FRANKLIN 0. EAST- MAN; residing in Cambridge, in the county of Middlesex, and ALBERT G. EASTMAN, residing in Brookline, in the county of Norfolk, State of Massachusetts, citizens of the United States-,have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This invention relates to window-screens, preferably to that class in which the screen is located in therun of the outside casing of the window and allows the lower sash to be lifted and lowered without any interference with the screen.

The frame of the improved screen is made of sheet metal or equivalent material and is 1 intended to be very strong and permanent, to

be easily applied, adjusted, and removed, and to be economical in construction. It comprises peculiarly-constructed corner-pieces, which are connected at the top, bottom, and sides by interlocking rails or bars of peculiar shape, the bars selected for a particular case being of the length required to enable the screen when its parts are allassembled to fit into a particular window-casing with economy of material.

The invention consists of the novel con the sashes of a window applied and the lower sash partially lifted, the casing being provided with our improved screen. Fig. 2 is a horizontal section taken through the bottom rail, portions being broken out. Fig. 3 is a perspective detail showing a corner without.- F ig.4 is a the netting, .with separated parts. perspective detailof a corner with the'netting applied and the parts assembled. Fig. 5 is view in elevation of all the parts in the en'-' tire screen with the exception of the netting separated, portions. of the top, bottom, and

side rails being broken out. Fig. 6 isa cross-' section' taken on.line,6,.Fig'. 5, withxthe parts assembled. Fig. 7-is a section taken on line 7, Fig. 6. Fig. 8 is a cross-section taken through the bottom rail for the purpose of illustrating the method of fastening. Fig. 9

is an enlarged detail, partly in cross-section and partly in elevation, the section being taken through the bottom rail, illustrating one of the lifts and its method of connection with the rail. are looking from the rear or outside of the window.

Similar letters of reference indicate corresponding parts.

a a, Fig. 2, represent the outside .portion of the casing CL of a window, of which a, Fig. 1, is the lower sash. Secured in any desired manner to the inner surfaces of the portion a of the casing just beyond the run a for the lower sash are two upright guide-plates, the portions A of which set against the easing, the portions A being bent inward at right angles from the portion A and thence curved around at A" and back at A' and forward with the inwardly-folded guide-lip A, as indicated in Fig. 2. The spacesv between the lips A and the portions A constitute vertical runways or grooves for theouter ends of hooks or clips which extend horizontally outward from the frame of the screen, said clips consisting, respectively, of thehorizontal shank B, outer portion B, bent' atright angles outward from the sh ank,and inwardlyextending lip' or hook B, and the shank O and parts o'and 0", substantially similar in shape to'the parts B and B. The clip B B B is yieldingly secured to the frame,"and the clip 0 O C is rigidly secured to the frame, and said clips extend through the opposite upright portions of said frame, all as below described.-

The frame of the screen comprises four corner portions which are substantially similar and which are connected with each other by intermediate bottom, top, andside rails. In pra'cticethe corner-pieces may always, if desired, be of the same size; but in assembling the. parts to produce a screenfor'agiven window theconnecting-rails are selected with reference to the width of the window and the desired height of the screen, andsaid cornerpieces and connecting-rails are adapted to intermesh and produce, when-the nettinghas been applied, a rigid frame'with'outthe aid of solder, although, if desired, a few small drops of solder may be applied. 1. 1,..1.

' The four corners of the'frameare' exactly In Figs. 3, 4, and 5 the views alike and each comprises an outer metallic portion formed into a channel shape and an inner metallic portion reversely formed into achannel shape, each made integral and turning or extending continuously around the corner. The outer portion consists of the web D, having its opposite edges bent inward (toward the sash) at D and D, parallel with each other, and thence bent outward into the lips D" and D", whereby grooves are produced between the lips and the portions D. By cutting out the web D at the point where the corner is to be formedsay on line (1 and d, Fig. '7cutting away also a sufficient portion of the inner fold D' and inner lip D, the outer fold D and lip D" of the web may be bent at right angles, the adjacent ends of the web D sliding by each other and the ends of the fold D and lip D abutting against each other and constituting a joint,where they may be united by a little solder, if desired. The inner portion consists of the web E, formed with the outwardly-projecting parallel portions E E and the inwardly-project.- ing lips E E", Figs. 3, 4, and 7. By cutting the web E and portion E E at c, Fig. 3, the portion E' and lip E" may be bent around at right angles, as shown, at the same time that the portions D and D are bent, the parts being assembled by slipping the lips E" and E', respectively, into the grooves formed by the lips D and D" before the bending process.

The corners above described have their ends connected by the top, bottom, and side rails all exactly alike and each consisting of a web F, opposite parallel portions 1 and lips F, said lips connecting the ends of the said corner-pieces by sliding into the same grooves in which the lips E and E lie that is, the grooves formed by the lips D" and D. Each of the bottom, top, and side rails has intermeshed with it centrally between the ends of the corner-pieces a web H, which has lips and grooves exactly like those described and illustrated in connection with the web D, the webs F and H beingintermeshed exactly like the webs D and E and filling the space between the ends of said webs D.

The wire-netting S is secured to the webs E by means of staples I, one leg of each of which extends through said web and clenches against the web D, while the other leg extends between the portion E and lip D. The netting may also be similarly secured to the webs F. The edges of the wire-netting and its fastening devices are concealed by means of covering-plates K, each of which is angleshaped in cross-section, whereby a lip K is produced, which is forced between the lips D and the portions E, connected, respectively, with the webs D and E, and between corresponding portions of the central rails, said covers being held in position by friction, although a very little solder may be applied, if desired, and thus producingafinish to that side of the screen and protecting the parts.

Preferably the vertical covering-plates are formed with rectangular ends and the upper and lower covering-plates with beveled ends. It will be observed that when the parts have been assembled thejoints are not coincidentin other words, the screen breaks joints.

Vithin the horizontal portions of the corners on one side of the screen spiral springs L are located, as shown in Figs. 2 and 5. One end of each spring is secured, by means of a suitable connecting-link L, to the web D, while the other end is secured in any suitable manner to the shankB of the clip B B B. The springs when in position are extended (not compressed) and pull, by means of the clips B B B and O O 0, against the hooked ends of the guides A A A" A instead of pushing against the sides of the window-frame, as is ordinarily the case. The screen is placed in the casing by catching the yielding hooks or clips on one side in the guide on that side and then, by stretching the springs, catching the stationary hooks or clips on the other side in the guides on that side. The screen may then be raised and lowered, the clips sliding in the guides. If desired, springs may be secured in the corners on both sides of the frame; but it is not necessary.

In order to facilitate raising the screen, we apply to the lower portion of the frame, preferably to the corners, swiveled hook-shaped lifts P, Whose shanks P are screw-threaded and may be poi nted,if desired,and are screwed forcibly (making their own thread) into and through the portions D and lips E and D and portion E against the portion E, as shown in detail in Fig. 9. Vhen these-hooks are not in use, they are swung parallel with the screen,as shownin fulllinesin said figure, and when they are to be used they are swung inward at right angles to the screen, as indi cated by the dotted lines.

Thus it will be seen that a metal screen is produced formed with corners each having two opposite webs of metal besides a covering-plate and nine thicknesses in vertical section, thus producing great strength, said corners being continuous at the bends in four thicknesses, the corners being'connected by strongintermediatebars,'each comprising two webs covered by a plate which extends from corner to corner and having nine thicknesses in vertical section, said intermediate bars interlocking and intermeshing with the corners and breaking joints, thereby producing an exceedingly strong, stiff, rigid, and almost indestructible frame for the screen. Moreover, the parts are quickly assembled, and in practice the corners may be all made of the same size, while connecting-pieces of different sizes may be kept on hand to apply to the corners -in making screens for windows of different widths and heights. The swiveled hooks P enable the screen to be readily lifted, and the friction of the clips in the guides produced by the tension of the springs holds the screen at any desired height.

ICO

The window-screen can be quickly repaired and supplied with a new netting or a duplicate'of any of its parts by withdrawing the covering-plates K, pulling out the staples I, and unscrewing the lifts P, thereby freeing the different parts.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is
